GEORGE L. BROOMHALL, OF PATERSON, NEW JERSEY.

LOCK OR STOP BLOCK.

SPECIFICATION forming part of Letters Patent No.304,697, dated September 9, 1884.

Application filed January 7, 1884. (No model.)

F0 all whom it may concern.:

Be it known that. I, GEORGE L. BRooM- HALL, a citizen of the United States, residing at Paterson, Passaic county, State of New Jer-- sey, have invented a new and useful Improvement in Lock or Stop Blocks, of which the following is a specification, reference being `had to the accompanying drawings, forming a part thereof.

The object of my invention is to produce a stop or lock block for blocking and locking cars on side tracks and switches-of such new construction as to remove all danger of cars 'locked or blocked therewith escaping from the shape of theV rail B, are provided withv suitable holes to accommodate a clutch-bar having depending lugs E. The clutch-bar is provided with au OperatingleVer, D, which .lever is centrally located on and secured to the clutch-bar, as shown in Fig. 2. The upper inner back part of the sides or plates A are suitably boxed out, so as to give ample room to the lever D to operate freely between said sides or plates, the top edges of which are provided with lugs N, said lugs having suitable holes to accommodate a lock, l?.

` One of the sides or plates is provided with a which the pinF may be placed in position and the operating devices assume the posi tion shown in Figs. 1 and 4. It will be seen that the pin, after passing through the hub G and clutch-bar, firmly secures the device in position to hold the cars safely on the side track, switch, &c.; but to guard against the danger of designing persons drawing the pin F and removing the block to allow the cars to escape from their positions on the switch, side track, &c., the device is provided with a lock, P, and may be securely locked thereby to the rail B, and thus remove all danger of the cars leaving the switch, side track, &c., to enter upon the main track, preventing thereby accidents, which so frequently occur where the cars are insecurely arranged on the switches, side tracks, Ste., and which from the jar of passing trains, pressure from high winds, downgrade, 85e., are rolled on the main track, endangering life and limb thereby.

My lock and stop-block, being portable,-niay be carried about from place to place where the same is needed.

Having described my invention and its operation, what I claim, and desire to secure by Letters Patent, is

The combination, with the stop orlock block A, having sides A', provided with curved inclines and holes, and a clutch-bar arranged in said holes, the clutch-bar having lugs and operatinghandle for operating said bar, and lugs, lock, and pin for locking and securing the device to the rail, of the rail B and wheel C, substantially as set forth.

GEORGE L. BROOMHALL.
